Section 173-204-350. Sediment quality standards inventory.  


Latest version.
  • (1) The department shall gather available data on sediments and produce an inventory of sediment sampling stations which pass or fail the applicable sediment quality standards of WAC 173-204-320 through 173-204-340. Sediment sampling stations which are evaluated for compliance with the sediment quality standards of WAC 173-204-320 through 173-204-340 and placed on the inventory shall be sampled and analyzed using the Puget Sound Protocols or other methods approved by the department, and shall use an appropriate quality assurance/quality control program, as determined by the department. The sediment quality standards inventory produced per this section shall be used by the department, and made available upon request to the public and other federal, state, and local agencies for the following uses:
    (a) To identify and target necessary source control activities, such as discharger monitoring, to eliminate adverse effects on biological resources and significant health threats to humans from sediment contamination;
    (b) To identify contaminated sediment cleanup sites per the procedures in WAC 173-204-500 through 173-204-590;
    (c) To establish sediment quality ambient monitoring program status and trends analyses and reports;
    (d) To identify the sediment quality of areas proposed for dredging, in-water construction, and other actions requiring federal, state, and/or local permits; and
    (e) To complete other uses consistent with the intent of this chapter, as determined by the department.
    (2) Sources of data. Sediment biological and chemical data shall be gathered by the department for review to produce and update the sediment quality inventory on a biennial basis. Data sources include, but are not limited to:
    (a) Sediment data collected by the department for the Puget Sound ambient monitoring program, compliance monitoring of permitted discharges, and special environmental investigations.
    (b) Sediment data submitted to the U.S. Army Corps of Engineers in support of dredging permit applications.
    (c) Sediment data collected to identify problem areas and needed source controls in Puget Sound as defined in WAC 173-204-200(20), other marine waters, and all low salinity and freshwater areas in Washington state.
    (d) Sediment data used or collected in compliance with chapter 70.105D RCW, and the Model Toxics Control Act cleanup regulation, chapter 173-340 WAC.
    (e) Sediment data used or collected in compliance with the federal Comprehensive Environmental Response, Compensation and Liability Act.
    (f) Sediment data collected as a requirement of a National Pollutant Discharge Elimination System or state discharge permit.
    (g) Sediment data derived from other studies including:
    (i) Federally sponsored monitoring studies.
    (ii) Special monitoring studies conducted by local and municipal governments, or private industry.
    (iii) Data derived through Washington state department of natural resources administration of use authorizations.
    (3) The inventory shall be updated and made available to the public on a biennial basis.
